Rotational Symmetry with Point Lights?
as Ratt said you can do it like so:

first: Shift - A -&gt; Add plane

scale, rotate, place it as you need it

add a light

select your plane and tap on vertices




Shift - select your light -&gt; now you got 4 lights which move with your plane

add an array modifier...now you got 4 x count lights ;)
